A "flow calorimeter" is used to measure the specific heat of a liquid. Heat is added at a known rate to a stream of the liquid as it passes through the calorimeter at known rate, then a measurement of the resulting temperature difference between the in flow and the out flow points of the liquid stream enables us to compute the specific heat of the liquid. A liquid of density 0.85 g//cm^(3) flows through a calorimeter at the rate of 8.0 cm^(3)//s . heat is added by means of a 250 watt electric heating coil, and a temperature difference of 15^(@)C is established in steady state conditions between the in flow and out flow points. Q. Specific heat of the liquid is
